Practice HESI Fundamentals Exam Questions
Question 1 of 5
A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?
Correct Answer: B
Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.
Question 2 of 5
A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg · 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.
Question 3 of 5
A nurse in a primary care clinic is assessing a client who has a history of herpes zoster. Which of the following findings suggests that the client has postherpetic neuralgia?
Correct Answer: D
Rationale: The correct answer is D: Report of continued pain following resolution of the rash. Postherpetic neuralgia is a complication of herpes zoster characterized by persistent pain that continues even after the rash has resolved. This pain can be severe and debilitating, affecting the quality of life of the individual. Choices A, B, and C are incorrect because linear clusters of vesicles on the right shoulder would suggest an active herpes zoster outbreak, purulent drainage from both eyes would indicate an eye infection unrelated to postherpetic neuralgia, and a decreased white blood cell count is not typically associated with postherpetic neuralgia.
Question 4 of 5
A nurse prepares an injection of morphine to administer to a client who reports pain but asks a second nurse to give the injection because another assigned client needs to use a bedpan. Which of the following actions should the second nurse take?
Correct Answer: C
Rationale: The second nurse should prepare a new syringe and administer the medication to ensure proper and timely pain management. Administering another nurse's medication without preparation could lead to errors. Choice A is not the priority as the medication administration should take precedence. Choice B is not recommended as the second nurse should not administer medication prepared by another nurse. Choice D is inappropriate as patient needs should not be compromised for medication administration to another client.
Question 5 of 5
A client is evaluated by a nurse regarding the use of a sequential compression device. Which of the following client statements indicates understanding of the device's purpose?
Correct Answer: B
Rationale: The correct answer is B because sequential compression devices are utilized to enhance circulation and prevent clot formation in the legs. Option A is incorrect because these devices are not primarily meant to prevent skin sores. Option C is incorrect because the devices do not directly address muscle weakness. Option D is incorrect as the main purpose of sequential compression devices is not related to joint health.
